Si160/160PFC

Portable in the shop or at the jobsite — at less than 6.2 kg (13.7 lb.) the shoulder strap allows the end user to easily move from location to location.

Inverter-based, DC power source has a simple-to-use operator interface providing only the necessary controls in a compact machine.

Dual fan technology. An optimised power source cooling system which enables the machine to operate at a lower temperature, thus increasing its performance and life cycle.

Thermal overload protection with indicator light helps prevent machine damage if the duty cycle is exceeded or airflow is blocked.

VRD function is a simple design that reduces the open-circuit voltage to 20 volts when the welding power source is not in use.

Best-in-class stick arc character istics for those demanding jobs.

Preset Hot Start™ for stick arc starts automatically increases the output amperage at the start of a weld should the start require it. Prevents the electrode from sticking and creating an inclusion.

PFC (power factor control) allows taking full advantage of the available input amps resulting in the required welding current without power leakage (Si 160 PFC model)
